Mark 39

“The B-52 [over North Carolina] was carrying two Mark 39 hydrogen bombs, each with a yield of 4 megatons. As the aircraft spun downward, centrifugal forces pulled a lanyard in the cockpit. The lanyard was attached to the bomb release mechanism. When the lanyard was pulled, the locking pins were removed from one of the bombs. The Mark 39 fell from the plane. The arming wires were yanked out, and the bomb responded as though it had been deliberately released by the crew above a target. The pulse generator activated the low-voltage thermal batteries. The drogue parachute opened, and then the main chute. The barometric switches closed. The timer ran out, activating the high-voltage thermal batteries. The bomb hit the ground, and the piezoelectric crystals inside the nose crushed. They sent a firing signal. But the weapon didn’t detonate.”

Readings: Ebola Papers, Check Your Science, Zimbardo’s Ugly Problems

reddit: Understand the Dynamics of Ebola EpidemicsFor the bored, curious, and comorbidly morbid, a handful of open-access papers on Ebola (mostly epidemiological in nature) available in this reddit thread. Possibly made more relevant by an index patient in Sierra Leone disappearing from the hospital, and the top Sierra Leonan ebola virologist coming down with the virus.

Also reddit: A toxicology professor from McGill did an AMA (“Ask Me Anything”) on his research into electromagnetic radiation and health effects. Redditors ripped apart his shoddy science and he basically refused to answer a single hard question.

BPS Research Digest: What the textbooks don’t tell you – one of psychology’s most famous experiments was seriously flawed

The SPE was criticised back in the 70s, but that criticism has noticeably escalated and widened in recent years. New details to emerge show that Zimbardo played a key role in encouraging his “guards” to behave in tyrannical fashion. Critics have pointed out that only one third of guards behaved sadistically (this argues against the overwhelming power of the situation). Question marks have also been raised about the self-selection of particular personality types into the study. Moreover, in 2002, the social psychologists Steve Reicher and Alex Haslam conducted the BBC Prison Study to test the conventional interpretation of the SPE. The researchers deliberately avoided directing their participants as Zimbardo had his, and this time it was the prisoners who initially formed a strong group identity and overthrew the guards.

Article goes on to talk about how the Stanford Prison Experiment is covered in top US psychology textbooks, which is less than inspiring. While I was studying the SPE was certainly regarded as a staple in psych education, a bit of a monolith. I should’ve known better!

Readings: Tea Party Congressman Is An Idiot, Tasers and Suicide Bombers, The More Media Changes

FP: Freshman Congressman Mistakes Senior Government Officials for Foreigners – “In an intensely awkward congressional hearing of the House Foreign Affairs Committee on Thursday, freshman Rep. Curt Clawson misidentified two senior U.S. government officials as representatives of the Indian government.” – Tea partier from Florida. Shocker.

Speaking of shockers, from the Journal of Forensic Sciences: Sensitivity of TATP to a TASER Electrical Output – “A series of experiments were performed to evaluate and document the effect of a TASER (“stun gun”) on triacetone triperoxide (TATP), an easily manufactured explosive used often in IEDs and suicide bombing vests…The TATP reacted in 17/17 tests when the TASER arced through the TATP and 0/4 times when the TATP was configured in such a way that the TATP was not subjected to the electrical arc. Based on the experimental data, TATP will readily explode in a variety of configurations by a TASER or similar device.” – The lesson here: don’t tase suspected suicide bombers, it’ll likely end up worse than tasing someone after they’ve been dosed with alcohol-based pepper spray (hint: they immolate).

And this fantastic find from @AdrienneLaF: ‘Complaints @nytimes had about the telegraph in 1858: “superficial, sudden, unsifted, too fast for the truth…”‘ –


Readings: Gameover Botnet Interview, Memory-Enhancing Implants, Snowpiercer Release

Krebs: Backstage with the Gameover Botnet Hijackers – “Defending a system that is as complex as this one is very hard. Complexity is the enemy of security. I won’t go into specifics, but let’s just say there are examples in the code where they clearly overreacted and introduced features that we could later use against them.” – An interesting lesson in the midst of a great interview, and a lesson that can be applied pretty broadly. Overreaction is an enemy in just about every field I can think of.

Ars Technica: Human memory-saving devices get $37.5m research boost from DARPA – “Both will initially work with people with epilepsy who have been given implants to locate where their seizures originate. The researchers will reuse the data gathered during this process to monitor other brain activity, such as the patterns that occur when the brain stores and retrieves memories.”

Verge: Post-apocalyptic thriller ‘Snowpiercer’ available for download just two weeks after release – ‘He added: “The motto at Radius is ‘a screen is a screen is a screen’ … We’re screen-agnostic, and as consumer habits change, film audiences today are becoming screen-promiscuous. Starting Friday, 85 million-plus consumers will have access to Snowpiercer on VOD. The film will be more widely available than every other film on screen this weekend combined. One way or the other, we’re going to find you somewhere.”‘ – Incredibly smart tactic on their part. Multi-platform releases that focus on accessibility and timeliness are a great step toward a really thriving digital future.

Readings: Domestic Cessna Spyplanes, Hotel Computers Keylogged, Sentient Teen It Was Not

BoingBoing: Airborne police surveillance is a PVR for every car-journey in a city – “A Dayton-based company called Persistent Surveillance Systems wants to loft Cessnas with high-resolution cameras over cities, setting them circling and recording all automobile journeys is 25 square mile areas.” – This seems like a fascinatingly extravagant plan in an age where similar drones are more or less available now, and the entire system could be much more easily implemented at ground level with much less sophisticated technology. I drew up a scenario a few weeks ago that did this using simple plate-reading traffic cameras, cross-referencing available law enforcement databases and geotagging entries into ‘investigational databases’ (which, scarily, exist). The Cessna angle seems like an end run around both FCC drone issues and regulations on aerial surveillance.

Krebs: Beware Keyloggers at Hotel Business Centers – ‘“The keylogger malware captured the keys struck by other hotel guests that used the business center computers, subsequently sending the information via email to the malicious actors’ email accounts,” the warning continues. “The suspects were able to obtain large amounts of information including other guests personally identifiable information (PII), log in credentials to bank, retirement and personal webmail accounts, as well as other sensitive data flowing through the business center’s computers.”’ – Great points by Krebs here on the near impossibility of reliably securing a computer to which attackers have physical access.

Verge: Google futurist Ray Kurzweil and other experts say chatbot didn’t pass Turing TestAs I figured earlier, the arbitrary nature of the test conditions leaned towards a pass for an otherwise unremarkable piece of software.

Readings: CDC Flu Debacle, Dark Wallet, Predator Alert

Global News: What happened at the CDC’s flu lab? – “But the USDA lab noticed that the virus that was supposed to be H9N2 wasn’t behaving the way they would have expected it to – which likely means chickens started to die. So they tested it to see what they actually had on their hands. And they discovered the CDC had sent by error a sample that also contained H5N1. In the lab world, this is a bad mistake to make.” – So an anthrax mistake, a smallpox mistake and now a flu mistake all happening in pretty short order for the government. What is going on here?

Wired: Waiting For Dark – “It’s May Day, every anarchist’s favorite holiday, and the two 26-year-olds have marked the occasion by releasing a piece of software that represents their best attempt so far to undermine every government in the world. A call from a lawyer friend has reminded them that creative US prosecutors might hit them with conspiracy or other charges. So they’ve decided to skip town.” – Interesting article on some possible next steps for bitcoin, and an interesting profile of two pretty prominent community figures. I don’t buy into the libertarian theology but the tech is worth diving into.

Lifehacker: Predator Alert Warns You If Your OkCupid Prospect May Be DangerousScript that relies on two different things: a self-report scheme and face recognition. The idea that predators would self-report honestly, either externally or within themselves, is a bit laughable. But the second mechanism by which the user’s dating website profile picture is run through the US Sex Offender Registry is a bit fascinating.

Readings: Hard-drive K9, Google DRM Problem, Fingerprint Dating

Ars Technica: Hard-drive-sniffing dog, Thoreau, is cops’ latest weapon on child porn – “Thoreau is trained to identify scents such as metals and other components found in these gadgets.” – Trotting out that old “child porn” argument again to justify any step towards the crackdown on undesirable technology. Given that you explicitly have no rights to data privacy when crossing the US border, I can easily see these dogs finding drives for border patrol to then copy and search without so much as reasonable suspicion, no less a warrant.

Also Ars: Google posts DRM workaround for paid Android Wear appsPaid apps for the new Android Wear system were unusable thanks to their being encrypted and Wear not being able to decrypt them. Amazing that even Google fumbles when it comes to Digital Rights Management restrictions. Another big sign that DRM is more of a hindrance than anything; a stumbling block in the important launch of a new product branch. Seems DRM just isn’t worth the hassle.

TYWKIWDBI: Dutch forensic experts can date a fingerprint – ‘Taking into account the temperature of the original prints’ surroundings, which affects the speed of deterioration, forensic experts can now date fingerprints to within “one or two days”, up to 15 days.’

Readings: Facebook Fumble, eSports Idiocy, Security Catastrophe

PP: Burglar busted after failing to log off Facebook, police say – ‘On Thursday, a resident returned to his home in the 600 block of Concord Street North in South St. Paul to find the residence in disarray, with a screen missing from a window and items including cash, credit cards, a checkbook and a watch missing from the bedroom. He noticed a wet pair of jeans and tennis shoes on the floor. He also noticed a Facebook page — “Nick Dub” — open on his computer.”‘ – The stupidity of this astounds me. Homeowner contacted the burglar to arrange a trade; stolen items for his jeans and shoes. Burglar showed up and was promptly arrested.

Destructoid: Gender segregation in eSports tournament ignites controversy – ‘…this was “in accordance with the International e-Sports Federation’s (IeSF) tournament regulations, since the main tournament event is open to male players only. This is to avoid possible conflicts (e.g. a female player eliminating a male player during RO8) among other things.”‘ – Again, amazed by the stupidity, albeit of a different sort. By seeking greater legitimacy as a sport they lose boundless legitimacy as an event worth participating in.
